I have the same ringtone for everyone. It sounds like a doorbell. I do have a special ringtone for unavailable or restricted calls. My experience with these types of calls have always been unpleasant (telemarketers, creditors), so I decided a good blues tune would be perfect to listen to when I get these calls. When I hear it I immediately know what type of call it is. I ignore the call and just sit back and enjoy the blues.
